Interesting. I did notice something yesterday, while looking at diffs = and looking especially for things in sparc64 or networking code, the following diff = committed to stable/10 in r262861: = http://svnweb.freebsd.org/base/stable/10/sys/sparc64/sparc64/machdep.c?sor= tby=3Ddate&r1=3D262861&r2=3D262860&pathrev=3D262861 ..which is a change to where console is initialized with respect to = the traptable being taken over. Not that I know it=92s related, but it is related to initialization of = the console w.r.t. muteness being initialized=85 - Chris
